需求背景: 查看一个公司数据后，需要看公司的注册地址在地图的位置，并导航过去或查看相关地图位置

Tips 👉：这种方式的好处就是直接调用手机自带的地图，不用锲入SDK进行操作，轻量化；

1、配置相对应地图app的LSApplicationQueriesSchemes白名单

· 1.1系统地图不用配置
· 1.2 高德地图 iosamap
· 1.3 百度地图 baidumap

2、判断是否能够打开URL，然后跳转链接即可.

#pragma mark - 导航目的地
- (void)openMaps {
    NSURL *gaode_App = [NSURL URLWithString:@"iosamap://"];
    NSURL *apple_App = [NSURL URLWithString:@"http://maps.apple.com/"];

        CLGeocoder *geoCoder = [[CLGeocoder alloc]init];
        NSString *address = @"北京市昌平区";
        [geoCoder geocodeAddressString:address completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
            if (placemarks.count > 0 && error == nil) {
                CLPlacemark *placeMark = placemarks[0];
                CLLocation *location = placeMark.location;
